Improvement in lamps



UNITED STATES PATENT OFFICE.

IMPROVEMENT IN LAMPS.

Specification forming part of Letters Patent No. 73,599, dated January 21, 1868.

To all whom it may concern:

Be it known that I, HIRAM W.HAYDEN, of Vaterbury, in the county of New Haven and State of Connecticut, have invented, made, and applied to use a certain new and useful Improvement in Lamps; and I do hereby declare the following to be a full, clear, and exact description of the said invention, reference being had to the annexed drawings, making part of this specification, wherein- Figure l is a vertical section of my said lamp as in use. Fig. 2 is an elevation of the same with the deflector and perforated air-chamber slipped down on the wick-tube, and Fig. 3is a plan of said lamp.

Similar marks of reference denote the same parts.

The object of this invention is to give access to the wick-tube Without disturbingr the chimney and allow the flame to burn without smoke or smell when turned down very low, so as only to continue a light as a night-lamp.

My invention consists in a perforated aircbamber and deflector united together and titted to slide upon the Wick-tube or guides, in combination with a chimney-holder that is supported by armsthat extend up from the burnercap. Thereby free access is given to the wick for trimming or lighting when the chamber and detiector are slid down, and when slipped up to the chimney-holder the parts operate in la manner corresponding generally to those in an ordinary lamp.

The deflector g is of a size to till the central opening of the ring chimney-holder d, and is formed with a flame-slot of the proper size and shape, but slightly larger than the wick-tube, to allow the said wick-tube to project through the same when in the position shown in Fig. 2. Below this deliector g, and united with it, is the perforated air-chamber h, formed of sheet metal, and foraminous both at the sides and bottom. An opening is made in the bottom of the chamber l1. corresponding to the wicktube, and a guide rod or rods, t', aid in keeping the detlector and air-chamber in position when slipped up or down, and a slight curvature in such guide-rod forms a spring` to hold the detlector and air-chamber when elevated.

When the parts are in the position shown in Fig. l the lamp will burn as usual; but there will be but little heat conducted to the cap a. When the parts are in the position shown in Fig. 2 a small dame may be burned without smoke or smell. The chimney e being undisturbed insures the required draft. There are no parts to become heated by being above the flame, and any vapors that might arise from the lamp are conducted into the llame by the detiector g and consumed.

In trimming the lamp any carbonaceous matters are excluded from the chamber h by the detiector g.

A thumb-piece, k, may be aftixed to the chamber h to facilitate the moving thereof.

What I claim, and desire to secure by Letters Patent, is-

A perforated air chamber, h, and detleotor g, fitted to slide vertically upon the wick-tube, in combination with the chimney-holder sustained by arms to the burner-cap, substantially as and for the purposes set forth.

1n witness whereof l have hereunto set my signature this 20th day of November, A. D. 1867.

HIRAM W. HAYDEN.
